Lets hope the CRZ battery is easy to remove then, anything that works and saves money is a huge plus
An Insight battery is monumentally difficult to remove due to the prototype nature of the car. It will take the average owner 3 hours to remove and reinstall. I did one recently: 20 minutes out and 30 minutes back.
The HCH was designed as a mass-market car and they fixed a number of the servicing problems of the Insight. The average owner can get the pack out and back in in about an hour. Most of that time is fighting with the seatbelts and the seat back. I can do a swap in 20 minutes flat (with a screwgun).
I'm guessing the CRZ will be closer to an hour than three hours.
With the Insight, Honda didn't expect to have to swap out the batteries (hence the "lifting tool"). They learned quickly and the Civics have straps attached to make them easier. Subsequent models (Accord, 2010 Insight) have easy access batteries. I see no reason why the CRZ won't also.
